Best Answer

Because of the word "cumulative". What that means is that the height of the graph for any value (X=x) is the number (or proportion) of observations that were less than or equal to the value x.

Now consider the cumulative value of the graph for a value of X which is bigger than x. All the previous observations were â‰¤ x and so they will be â‰¤ the newer, larger value. So the height of the cumulative graph cannot decrease. It may increase if there are any observations whose value was between x and the new value.

It will show you whether it is a constant rate or if it speeds up or slows down.

in a maths question, you have a table. you add up the frequency column, but every time you add something, you write it down, e.g. frequency cumulative frequency 1 1 5 6 3 9 6 15 and so on :)

a continuous line graph is a graph that is similar to a broken line graph but it always grows higher and higher it never goes down. e.g. age

it is a down on the graph

Up-link freq is higher than down-link freq in GSM You answer is wrong Correct answer is that, down-link frequency is greater than the up-link frequency in GSM. Up-link Frequency = 890 MHz - 915 MHz Down-link Frequency = 935 MHz - 960 MHz
